Braking and stabilising systems  
Overview  
the START-STOPP system.  
Auto Hold is activated.  
Stabilisation control (ESC)  
The automatic transmission mode is not selec-  
ted.  
ESC helps to stabilize the vehicle in borderline situa-  
tions (e.g. when the vehicle starts to skid). ESC  
brakes the individual wheels to maintain the direc-  
tion of travel.

NOTICE  
Disable Auto Hold to allow the vehicle to roll if nec-  
essary when driving through a car wash.  
Traction control (TCS)  
ASR helps to stabilize the vehicle when accelerating  
or driving on low-grip roads. ASR reduces the drive  
power transmitted to the wheels when the wheels  
spin.  
flashes - ASR is engaged  
Antilock braking system (ABS)  
ABS helps maintain control of the vehicle during  
emergency braking. An ABS intervention is noticea-  
ble by pulsating movements of the brake pedal.  
Motor Slip Regulation (MSR)  
MSR helps to maintain control of the vehicle in the  
event of a sudden reduction in speed, e.g. on icy  
roads. If the drive wheels lock, MSR increases the  
engine speed. This reduces the braking effect of the  
engine and the wheels can rotate freely again.  
Electronic Differential Lock (EDL)  
EDL helps to stabilize the vehicle when driving on  
road surfaces with different grip under the individual  
wheels. EDL brakes a spinning wheel and transmits  
power to a different drive wheel.  
Electronic Differential Lock (XDL+)  
XDL + helps to stabilize the vehicle during fast cor-  
nering by braking the inside wheel of the driven axle.  
Active steering assistance (DSR)  
In difficult situations, the DSR provides the driver  
with a steering recommendation in order to stabilise  
the vehicle.  
Hill Hold Control  
Hill Hold Control helps when starting off on uphill  
gradients by braking the vehicle for about 2 seconds  
after the brake pedal is released.  
Operating conditions  
The gradient is at least 5%.  
The driver's door is closed.

goes out on renewed activation.  
Multi-Collision Brake (MCB)  
MCB helps to decelerate and stabilize the vehicle af-  
ter a collision with an obstacle. This reduces the risk  
of further collisions.  
Troubleshooting  
Operating conditions  
There has been a frontal, side and rear collision of  
a certain severity.  
The impact speed was greater than 10 km/h.  
The brakes, ESC and other required systems re-  
mained functional after the impact.  
The accelerator pedal is not pressed.  
ESC or ASR faulty/deactivated by the system  
illuminates  
Stop the engine and start again.  
If the indicator light does not go out after covering  
a short distance, seek the help of a specialist ga-  
rage.  
ABS faulty  
Trailer Stability Assist (TSA)  
illuminates  
TSA helps to stabilize the trailer. As the trailer begins  
to lurch, TSA stabilizes the trailer by slowing down  
the individual vehicle wheels.  
You may continue driving, exercising appro-  
priate caution. Seek the help of a specialist garage.

chased from ŠKODA Genuine Accessories.

Electromechanical brake booster (eBKV)  
eBKV (electronic brake force distribution) facilitates  
operation of the brake pedal.  
Stop driving! Seek the help of a specialist ga-  
rage.  
After switching off the ignition, the eBKV (electronic  
brake force distribution) function is either restricted  
or not available.  
Front Assist  
Functionality  
If the vehicle is decelerated using an assistance  
system, pulsating movements of the brake pedal can  
occur.  
Front Assist monitors the distance to the vehicle  
ahead and points out when the safety distance is ex-  
ceeded. In borderline situations, it helps to avoid a  
collision by braking interventions.

Deactivating the ASR may be helpful in the following  
situations:  
Driving with snow chains.  
Driving in deep snow or on very loose ground.  
Starting up a vehicle that is stuck.  
At a driving speed of up to 30 km / h, the vehicle is  
braked without prior warning.  
Automatic braking can be stopped by pressing the  
accelerator pedal or by a steering intervention.  
Activate/deactivate ESC Sport  
Press the button under the Infotainment.  
With automatic braking, the pressure in the brake  
system increases. The brake pedal cannot be operat-  
ed by using the pedal as normal.  
In the displayed menu in the Infotainment, the func-  
tion can be deactivated or activated.  
When deactivated, lights up in the instrument  
cluster.

The vehicle is making a sharp turn.  
The vehicle is travelling on a sloping road or in ruts.  
When the driving lane is too narrow.  
Stationary vehicle  
The vehicle drives through a construction site.  
WARNING  
Be particularly attentive and alert in the following  
situations.  
Regulation according to the vehicle in the adjacent  
lane  
If your vehicle is moving faster than the vehicle in  
the next lane on the driver's side, at a speed of more  
than 80 km/h, this may cause your vehicle to be con-  
trolled according to that vehicle.  
If a vehicle in front turns and there is a stationary ve-  
hicle in front of this vehicle, the ACC must not re-  
spond to the stationary vehicle.  
When cornering

A load or superstructure that protrudes outside the  
vehicle might not be detected by the ACC.

Function restriction  
The system function may be restricted in the follow-  
ing cases:  
Lane Assist  
Usage  
The field of view of the sensor is limited by a dirty  
screen or an obstacle or a preceding vehicle.  
Lane Assist helps to keep the vehicle within the lane.  
It is based on the boundaries of a lane. These may in-  
clude lane markings, road edges or objects such as  
curbs or possibly traffic cones.  
If the weather conditions are unfavourable.  
The vehicle is making a sharp turn.  
The vehicle is travelling on a sloping road or in ruts.  
When the driving lane is too narrow.  
The system is intended primarily for use on high-  
ways.  
The vehicle drives through a construction site.  
WARNING  
Danger of incorrect steering intervention!  
Certain objects or markings on the road may be erro-  
neously recognized as lane markings.  
Functionality  
As the vehicle approaches a lane marking, the sys-  
tem executes a steering movement in the opposite  
direction from the lane marking. The steering inter-  
vention can be overridden manually.  
Always keep your hands on the steering wheel and  
be prepared to override the steering intervention.
